Here's a quick render of Thorin Oakensheild's Key of Erebor.This was actually a 3D model for 3d printing. There was a promotional thing where you could download and print your own replica, however it was rather low quality. This was one someone had done and is a lot better, even if the proportions are off a little.

I modifies it somewhat, rendered several passes in IFW 2.0 and composited in photoshop
